WATER-PROOF COMBINED COUPLING AND CUT-OUT FOR ELECTRIC CIRCUlTS.

SPECIFICATION' forming part of Letters Patent No. 448,679, dated March 24, 1891.

Application tiled November 3, 1890.

To all whom, t may concern. v

Be it known that I, FRANK SHLAUDEMAN, of Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Tater-Proof, Combined Couplings and Cut-O nts for Electric Circuits, of which the following is a specification.

This invention relates to water-proof couplings and cut-outs for electric circuits; and it consists in the details of construction and combinations of parts hereinafter set forth and claimed.

In the drawings accompanying and forming a part of this specication, Figure 1 is an external representation of a coupling and switch constructed in accordance with my invention. Fig. 2 is a vertical section of the coupling' and switch shown in Fig. 1 on a plane parallel with the plane of such figure. Fig. 3 is a similar section taken on a plane at right angles to the plane of Fig. 2. Fig. 4 is a diagram of the circuit independent of its surroundings, the point of sight being the same as in Fig. 2; and Fig. 5 is a similar diagram from the same point of sight as Fig. 3. Fig. 6 is aperspective view of a side and face or outer end of an insulating guide-block. Fig. 7 is aperspective view of the side and rear or inner end of the insulating guide-block. Fig. 8 is a perspective view of the cut-out cylinder.

rlhe pipe 1 is water-proof, and it contains circuit-wires which extend through lateral 2 and a T 3, or through an L, as Athe case may be. Socket 4 is fitted on lateral 2, and it has the flanges slotted at 5, to admit couplingbolts 6. The socket 7 has flanges 8, slotted at S, to conform to slots in iianges 5.

9 and 10 are insulating-washers in the inner ends of sockets 4 and 7, respectively.

11 and 12 are insulating guide-blocks for circuit-wire terminals, the one in socket 4 and the other in socket 7.

13 is a water-proof pipe extending from socket 7 and carrying circuit-Wires to a lamp 14 or other objective point. Plate 15is fixed on the shaft 26L of cut-out cylinder 2G. Its lower surface is curved concentric with the shaft. It has the stop projections 1G 1G, and also has the upward extension 17, provided with pin 1711. The pin` 29 project-s from socket 7, forming a stop for plate 15, and

spring 18 connects with such pin and with Serial No. 370,162. (No model.)

pin 172 Rodslf) and 19 connect one with each upper corner of plate 15, and chains 2O 2On depend from the rods to an easily-accessible point. The circuit -wires 21 extend through a central hole in guide-block 11 and connect on the face of such block with wires 22. Tires 22 return each througha separate side hole in the guide-block and connect at the inner end of such block with elastic spiral coils 23. The coils each extend through a vseparate side hole in the guide-block and terminate in bearings 24, which rest against the cut-out cylinder. On the opposite side of the cut-out cylinder bearings 24L continue the circuit to coils 23, connecting-wires 22, and circuit-wire 21a, all of which are arranged in block 12, as the corresponding parts are arranged in block 11. The cylinder 26 is an insulator; but it has the conducting-rings 27 in line with the termin als of the circuit-wires. The rings have segments depressed, as seen at 27 J in Fig. 8. The rings are narrower than the faces ot terminals 24, and when the cylinder is turned with the depressed segments of conductors presented to the terminals the faces or bearings thereof rest on the insulator out of contact with the conductor. The shaft of the cut-out cylinder has bearings 8b in the iianges of socket 7, and the cylinderis secured to the shaft by a pin or similar means. A gasket 30 surrounds the cylinder-shaft and iits between the plate and the iiange. A spring 2S bears against an end of the cylinder, and by forcing the shaft inward holds the gasket in close contact with its bearings and excludes moisture. In Fig. 4 31 and 31 show the junctions between circuit -wires and the wires that connect with the coils, such junctions bein g -made on the easilyaccessible faces of the guide-blocks. The rubber gasket 32 ts between the ilanges, and when the iianges are drawn together by securing-bolts forms a moisture-excluding joint. A description has been given of but one line of circuit-wire and one guide-block, for the reason that the disposition of both circuit-wires is the same, though separate, and the only difference in theguidc-blocks is the comparative shortness of 12, which is so made as to leave space for the cut-ont cylinder.

The cut-out cylinder is operated by the chains in an obvious manner, and the spring IOO 1S acts to complete a shift after the same is more than halt' completed.

I claim* 1. The combination, with the two sockets, the interposed gasket, and the coupling-bolts, of the cut-out cylinder having bearings in one of the two sockets, a gasket around the projecting` end of the cylinder-shaft, a spring bearing against the cylinder and acting indirectly on the gasket thereof, and circuit-Wire terminals bearing against the cylinder on opposite sides of the saine, as set forth.

2. In electric cut-onts, the combination of the insulating-cylinder, the conducting-rings in the cylinder, having segments depressed, and circuit-terniinals,wider than the conducting-rings, bearing against 'the cylinder in line with the rings, as set forth.

3. In electrical cut-outs, the combination of the cut-ont cylinder, the plate 15 on the shaft thereof, having the stop proj ections 16 1G and the extension 17, the pin 17u, projecting from the extension 17, the stop-pin 20, the spring connecting pins 17 and 29, and the lines conneeted with the plate at opposite sides thereof, as set forth.

In testimonyWhereoflsign my name in the presence of two subscribing Witnesses.
